Intermittent disconnection from network

There are several "communities' this might fit into, so please let me know if this question would be better suited to a different location.
I recently replaced my late-2006 MBP and am planning on giving it a long retirement as a home server.  The goal at first is to just use it for time machine backups and file serving.  I'll eventually add VPN and maybe web services, but that's a little ways off.  I read through Apple's documentation on setting up OSX server as well as sever guides online and think I have a good understanding of how this all works.  After much experimentation, however, I've hit a brick wall.
The specs are:
Mid-2006 MBP
Using Wired Gigabit Ethernet only (and have duplicated these results using wifi only and different CAT5/6 cables)
OSX 10.7.x + Lion Server (have also tried installing 10.6 server and duplicated these basic results)
Actiontec MI424WR-GEN3I router
I have Verizon Fios so I have to use their provided router.  I've set up a static IP for the MBP using the eternet device's MAC address on the router, but I get interesting (to me at least) behavior based on how I set up the DHCP configuration on the MBP.
If I just set up the static IP in the router's distribution table and let the MBP connect over simple automatic DHCP, both the MBP and the router seem happy:
If I set the MBP's network settings to DHCP with Manual Address, the Router shows the
When the connection is eventually dropped, the connection's status in the router's various tables and status areas will change to "inactive" if the MBP is set to the first condition (regular DHCP) or stay as expired (or just not show up at all) depending
Once the server's connection is dropped nothing short of a full restart will restore connectivity.  I cannot acccess it via screen sharing, renewing the dhcp lease provides no change in connectivity, logging out/back in is useless, etc.  If I restart the MBP, everything will come back just fine until after some random period of time when the connection is once again lost.

  • I have two problems with my 2012 13" MacBook Pro. 1. Gray screen shows at startup  2. Randomly disconnects from network. Any help will be greatly appreciated.

    I have two problems with my 2012 13” MacBook Pro.
    Gray screen shows at startup
    Randomly disconnects from network.
    Any help will be greatly appreciated.

    First, open Terminal in your Utilities folder and paste this into the prompt line:
    sudo update_dyld_shared_cache
    Press RETURN. You will be prompted to enter your admin password which will not be echoed to the screen. Press RETURN again.
    Next, boot the computer into Safe Mode.
    Next, do the following:
    Reinstalling Lion/Mountain Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • Sending mails while disconnected from network

    Hi All,
    We have a Desktop Application in which we will send few emails when ever user does some activity.We are using a open rely mail server at our side and configured the same in this application to send those mails. As this is a desktop application user may not be connected to internet all the time that he uses the application.All the users are configured to their outlook to use the mailing services.
    Now we have requirement that we need to send the emails even when the user is disconnected from network. As a java programmer i know that it's not possible to send the mails if the smtp host is not reachable. I am thinking of an alternative like some how if we can QUEUE the mail into the users outbox of his outlook when user is disconnected. So that when user is connected to internet all the mails will be delivered with out a fail.
    But I am not sure how to do this. Please help me if we can do this or any other alternative.
    Regards,
    Krishal.

    It's possible. It's only software, after all. But you're going to have to
    do most of the work yourself.
    The simplest solution would be to just run a mail server on the same
    machine as the JavaMail application, and let the mail server do the work
    of queuing the message and retrying it when necessary.
    If you don't want to run a mail server, you can build similar functionality
    into your application. Save the messages using Message.writeTo when
    you can't send them. Arrange to processed the saved messages at
    the appropriate times. Read them back in and send them.

  • Application 11i doesn't run if disconnected from network

    Hi,
    I've installed Oracle Applications 11i (11.5.10.2) on Windows Server 2003 on the laptop. It works fine while the laptop is connected to network but does not run if laptop is disconnected from the network. Could anybody tell workaround? Thank you!

    Hi,
    You must use a dummy network adapter called loop back adapter and configure ur ip on it,Remember with this u can only acess the apps on the local system nobody can connect from network.
    check in the forum by searching loopback adapter or google it for installtion

  • Why do I get the error message "iTunes Match could not download because disconnected from network?  I'm connected to the internet during that time with Safari so am I not connected to the network?

    Why do I get the error message "iTunes Match could not be updated because you were disconnected from the network during processing."  I'm on the internet during all of this.  What disconnect is the message referring to?  Itunes is frozen now.  I keep clicking OK but it just comes back with no action.

    Hello FredJay,
    Thank you for contacting Apple Support Communities.
    iTunes Match needs a network connection to work, either Wi-Fi, cellular or wired. See the following:
    Make sure you have an active Internet connection
    Be sure your computer or device has an active Internet connection by loading a webpage using Safari or another web browser.
    On an iOS device with cellular support, if you are not on a Wi-Fi network, try enabling 3G cellular data1 for iTunes Match.
    For iOS 6, tap Settings > iTunes & App Stores > Use Cellular Data > On
    For iOS 5.1.1 or earlier, tap Settings > iTunes & App Store > Use Cellular Data > On

  • Indesign disconnects from Networked server

    I have Indesign 6 installed on a macintosh 10.6.8 and always work from files on the server. Indesign is part of the creative suite 6 with the latest updated. The issue I am having is that if I don't use the software for about half an hour it disconnects from the server; if I go for lunch and leave an artwork open, to only way of getting it back is to force close indesign and restart the software and the file is recovered. Does anyone know if Indesign creates a cache file on the hard drive - I think this may be the issue as it does not exist in any folder. If there should be one such file, how to I recreate it or anyone knows how to repair indesign without re-installing it. Thanks.

    This is a well-known problem with ID and network connections. The best advice I can offer is don't leave files open and leave the machine.

  • Disconnection from network

    We have a mixed Mac-PC network at school with three wireless nodes using HP ProCurve bases. Two of them work well with Macs, however since we put into place a password protected sign in the one I use has had intermittent problems by disconnecting my computer from the network. I can get around this by renewing the DHCP lease in the system folder but this is a pain. Our IT person is only PC and simply tells me to sell the mac and get a PC. Any suggestions would be helpful,

  • Wireless printer disconnecting from network

    Hello all,
    Here is my problem.  I have a new HP 3510 set up as a wireless printer on my home network.  I have three computers, two wired and one wireless.  I have a netgear router for 3G air card.  I can connect my printer to the network initially.  I can print from any computer, initially.  I can even use ePrint.  The trouble is that the next day, when I fire up any of my computers that printer is no longer on the network.  I have upgraded the router firmware, and the trouble seems to be there.  When I power cycle the router, everything is connected once more.  I have set a static IP on the printer.  Furthermore, and have tried setting the printer as a static IP within the router.  I am now at a loss.  I have read about setting the DHCP range on my router outside the printer IP.  Would this even make a difference?  Since I am not sure what is happening, I do not know if this will help any.  It acts like either the router or the printer are going into a sleep mode or something, however, my phone is also connected on the network, and when I get home it immediately connects.
    Thank you in advance for the help.
    FYI: the two wired computers are XP and Win7.  the wireless is Vista
    I have wpa-psk + wpa2-psk set for my router security.  Have not tampered with the router firewall, but since the printer connects initially, not sure if that would be the cause.  I have set the printer IP well above anything that has been used by any other networked hardware.

    Hi, unless you reserve the static IP in DHCP it is best to assign a static IP outside the DHCP range.

  • Thunderbolt display disconnects from network when asleep

    I have a MBP 15" (Retina) connected to a Thunderbolt Display. I'm using the Ethernet connection on the display and "docking" the MBP with the Thunderbolt connection. Every time my MacBook Pro goes to sleep, I lose all my network drives. I don't get an error on the Mac/Finder side, but all my Windows Explorer (through Parallels) windows produce an error about losing the network location. The open windows in the Finder simply go back to the Home folder -with no errors- and my shortcuts back to the network locations work as they should. The same thing happens on the Windows side, albeit with an expected error message; all mapped drives have a red X, but clicking on shortcuts restore the connections.
    I'm running the latest version of OSX, the latest version of Parallels and Windows7.

    No, the computer must be on.

    my apple tv is disconnected from the wifi intermittently, the problem is not the wifi as it only happens to the apple tv. that I can do to fix this problem.-

    That doesn't rule out a network issue, as it can impact devices differently. Intermittent issues are most often related to wifi issues. Try connecting via ethernet. Go to istumbler, netstumbler or similar to get a report of the network, look for signal strength and noise.

  • Constant Disconnection from Cellular Network

    Hi There, so I've gotten my iPhone 5 32GB since July 2013 and I honestly adore the phone however, there is a problem i'm facing with it quite recently.... the phone keeps disconnecting from the cellular network carrieer every 10 secs of the day... so...I'll start up the phone it connects with 5 blocks of reception.. then it drops to four...then to 1... then it completely disconnects itself from the network and the Edge sign disappers and then 5 secs after it connects back. I dont use my phone much to talk.. however.. it messes up my data plan, i can't even make a call that is more than 10secs... it drains the battery life and I have to wait every few secs to send a whatsapp mesg/fb etc. . I spoke to my carrier... they used different sims of the same network to see if its the sim card itself being the issue.. but its not.. we even used another network's sim.. but no difference.. What should I do?
    Sincerely, Stefan (first time Apple user)

  • Constant Disconnection from Airport Extreme Networked iMac (late 2009)

    I keep trying to copy fairly large files (2-7GB) over my Aiport Extreme (latest—5th generation) network from a early 2011 Macbook Pro to a 27" iMac (late 2009), and I keep getting disconnected from the iMac while the file is copying. I've tried repairing permissions on every computer in the house and restarting them, but I'm still having issues. I have no issues copying files to another late 2011 Macbook Pro in the house, so it seems to be happening only when I copy them to the iMac. The iMac is running Snow Leopard and the Macbook Pros are running Lion, so could that have something to do with it?
    Additionally, I had been trying a wireless extended network with another previous generation Airport Extreme, but I found the connection wasn't much stronger with the extension, so I've just been leaving the second Airport Extreme unplugged. I've had that unplugged for months and haven't had any issues, so I don't think that's the problem.
    I'm hoping this isn't a sign of something being wrong with the Aiport card in the iMac. Anyone have any ideas?

    Bump?

  • Disconnection from cellular network

    since i've bought my new 3gs this week it keeps disconnecting from the network if i keep it without usage for about some time ..approx 30 min or more....when some one calls me he finds me out of service and when i call some one the call fails and i have to restart the phone to once again get connected to the operator and can make and receive calls normally
    i tried everything reset network settings, reset all setting, choose carrier manually, i restored the whole OS from i tunes (3.1.3) but nothing worked the same problem occurs..note that am using it on 2g and closing 3g as i have weak 3g in my area...
    am really tired from that issue..please any help that would be great!!

    If the issue is consistent and you say youve done all the steps youve listed my best advice would be to return the iphone to your nearest apple store.

  • MBP Airport consistently disconnecting from the Web, but not the network

    My MacBook Pro Airport has been cutting in and out - or at least the Web access has - when I use it in combination with a DLink router. The local wireless network connection always seems to stay connected (or at least it says it's connected), but I can't access the Web. It has shown these symptoms when used in combination with other routers too, but only when I use it with the DLink first and then move to another network.
    I can sometimes fix the problem by a combination of restarting OS X and resetting the PRAM, and restarting the router. However, this doesn't always fix the problem, and even if it did, I'd probably be doing it at least once a day with the current frequency of disconnections. So I'd like to get to the route of the problem.
    An ethernet connection to the DLink router always works without a hitch.
    Does anyone have any suggestions or any knowledge that might help resolve this?

    Just remembered I have the 'self assigned IP' error too. There seems to be a fair few posts about this issue. I haven't found a definitive fix yet, but these posts might hold some clues;

    http://discussions.apple.com/thread.jspa?messageID=6708778&#6708778
    The second post suggests applying the 'Disconnect from wireless network when logging out', which I've applied, because I've noticed that I often see the problem when I put my MBP to sleep.
    p.s. Last year I quick-fixed this issue by attaching a Buffalo wireless router to the network as an extension and connecting to that instead of the Dlink. But I just gave the Buffalo to someone, having forgotten about the issues with connecting to the DLink.
